R/B Item Pack and Storage Limits

Hello,

I've been playing Red on my 3DS (US) and recently hit the limit of items in my PC. I was hoping there was a good way to get around that (with as little risk to my data as possible).

I read the expanded item pack page in the wiki, but from what I understand, the added slots are accessible parts of memory that affect the game in manipulating them? That it's not really something meant for actually holding your items.

Is there maybe some safe zones in the item underflow for holding stuff? Or maybe something that might help me semi-accomplish my goal. I'm mostly hording TMs I've duplicated, and so maybe a good way to re-get TMs once tossed/used could be the next best thing?

Thank you for taking the time to read. :) I look forward to any insight on dealing with these things.

Every item above 50 in the Expanded PC is a byte of the WRAM and manipulating such items will manipulate game-related data. Now here is what item deals with what, starting from 52 as 51 is the end-of-list marker.:

52: Active Pokémon box (2nd byte). Its quantity matches the number of teams in the HoF.
53: Unused (or currently unknown) byte. Its quantity matches the first two numbers of the Casino Chips (BCD)
54: Two last numbers of the Casino Chips (BCD)
55 to 91: Missable Objects Flags (current status of any pickable item of the game)
92 to 255: Event Flags

I wouldn't recommend to use event flags as you have all chances to f*ck your game up at some point, but you can use item 53 as an extra slot, also 54 if you don't care about Casino Chips. Missable objects flags slots could be used, as if you already picked the items the only side effect will probably be to bring them back. But it has some issues as for example, Snorlax is an item, so messing with these slots can put it back (which might or might not be annoying to you).

If you wish to do that and since you already seem to have 50 items, instead of doing complicated stuff with MissingNo. you can also quickly perform the Glitch City RAM Manipulation to expand the PC to 109 items.

You won't have to hoard TMs since you can always get whatever you want from your expanded item pack using one of the numerous RAM manipulation tricks.

Also, your rival's name (items 23-27) is a good place to store items, unless you want to complete your game normally (then you'll have to fight your rival at some point).

Thank you both for the input, Krys and camper. :)

I suppose an actual "expanded item pack" is not really possible then, not without botching some things, which I'm trying to avoid for this particular VC gamepack.

This sounds like a better route to try to go.

The Gitch City RAM Manipulation glitch that Krys shared seems like it might be limited in doing something like this. Any ones that you think might fit better in this situation?

I think I'll probably try to play with these in a ROM or a different gamepack before doing anything on the actual game in question, if I can find a decent one. 8F looks interesting, but I'm iffy about the Pokedex corruption that comes from it.

Else, maybe I'll just have to deal with the limited space and just toss the TMs that aren't so good (Water Gun, Mega Punch, etc.). Maybe see about tossing things like the S.S. Ticket.

Being kinda picky with this particular save, I know. Just how it is for this case.

If you want a RAM Manipulation trick related to the item underflow glitch, that allows you to get any item, you can use the Celadon Loop Trick which is described in the 8F thread. It involves triggering the underflow and switching a given item with the 35th item. We traditionnally use this to get the 8F item, but each step gives you a different item.

What kind of corruption are you talking about?

Oh, I think I may have misread something in the 8F thread. The Pokedex corruption is only a side-effect for one of the processes for getting 8F that is not recommended. Not for using 8F. My mistake. Glad that's all cleared up!

So it only botches the player name when you use 8F? But that's fixable, and so long as that doesn't cause any trouble, that's not too bad.

I will definitely check that Celadon Loop Trick out though. Thanks, Krys! :D That sounds like it might be a bit nicer.

It makes me think of a question though. Does item underflow mess with using the items one has or in picking up new ones? I read in the wiki that buying 3 items will return your pack to normal, though you'll lose the first one.

Hello again,

Nothing is botched by USING 8F.

Some obsolete and unrecommended methods that are used to GET 8F can mess up things (your name in the case of Super Glitch corruption, the Pokédex in the case of Cooltrainer corruption or save abuse related stuff), but nothing unfixable as you can fix everything once you have the 8F item. And it's not even an issue, since you actually don't mess ANYTHING by getting 8F with the Celadon Loop Trick ; but indeed you will lose your items, which is why it is recommended to store everything in the PC except for a useless item (like Poké Ball x1) you can buy specifically for the trick.

OK, thank you again, Krys! :D Much appreciated. I am really excited to try playing with it then.
